This is a milk preparation pot that can keep water warm at 70 degrees Celsius. It was helpful for nighttime feedings. I used it for about one month for each of my first and second children until their milk supply stabilized. Therefore, it has only been used a few times. There is no scorching or other damage on the heating surface. The glass is in clean condition with no noticeable scratches or stains. The instruction manual is not included. As this is a used item, please refrain from purchasing if you are sensitive about such things. ——-Product Description Below——- [Milk Preparation Pot 70 HW] ● A milk preparation pot that keeps water at 70 degrees Celsius or higher, making it easy to cool and hygienic. ● Simply pour boiled water in, and it will automatically maintain a temperature of 70 degrees Celsius or higher, suitable for milk preparation. ● Effortless milk preparation even in the middle of the night! ● Easy to handle not only for inexperienced mothers but also for new fathers, allowing for smooth milk preparation. ● A spout designed for optimal pouring into baby bottles ● The duckbill-shaped spout allows for precise pouring of hot water, making it easy to transfer to baby bottles. ● Easy heating in the microwave ● You can easily heat water in the microwave-safe glass pot. ● Long-lasting warmth with a cover ● The pot is enclosed by a cover, which reduces heat loss from the surface and maintains a water temperature of 70 degrees Celsius or higher, optimal for milk preparation, 24 hours a day.
